Wednesday’s all-weather fixture at Newcastle has been called off due to snow.
The venue was due to stage a seven-race card, but overnight snow forced clerk of the course James Armstrong to take an initial look at 8am, before checking conditions again at 10am.
That second inspection showed the track was not fit for action and Armstrong abandoned the fixture, with an inspection called for 10am on Thursday ahead of the planned evening card.
Armstrong said: “We’ve had something like three inches of snow, but it’s powdery, dry stuff. It’s cold, the temperatures aren’t going to start rising until later this morning and there’s the possibility of more snow.
“We’ve worked the track, but it’s got into the surface profile and it’s starting to ball up a bit, so it’s a fairly easy decision to make really.
“We’ll inspect at 10am for tomorrow’s meeting. We’ll use the windows of sunshine today to work the track and try to help it thaw out.”
Wolverhampton’s evening card was also subject to a 10am check, but the fixture got the go-ahead.
There will be no jumps action in Britain on Thursday though, as Ffos Las’ meeting has been called off due to a frozen track.
Officials had hoped to escape the worst of the overnight freeze and called a precautionary inspection for 8.30am on Wednesday.
However, that check showed the track to be unraceable with little prospect of sufficient improvement.
The course tweeted: “Despite the huge efforts of our ground staff team to cover the course, tomorrow’s race meeting has been abandoned – parts of the track are frozen and temperatures are not forecast to rise sufficiently for it to thaw.”
Thursday’s Thurles card is also under threat, with a precautionary check planned for 7.30am on race day.
An Irish Horseracing Regulatory Board statement said: “Due to a Status Yellow weather warning in place for snow and ice, there will be a 7.30am precautionary inspection at Thurles tomorrow (Thursday) ahead of the fixture scheduled to take place.
“The track is currently fit for racing and the going is soft (chase) and soft to heavy (hurdle/bumper).”
